Abstract: A variable area vane arrangement includes a stator vane, a bushing and a vane platform with an aperture. The stator vane rotates about an axis, and includes a shaft that extends along the axis into the aperture. The bushing is connected to the shaft, and is arranged within the aperture between the vane platform and the shaft.

Abstract: A method of evaluating an article includes measuring a feature of the article using a defect detection device. A set of data points is recorded representing the first feature and the set of data points is analyzed. The analyzing includes constructing a filtered curve by constructing a raw curve by listing the set of data points, constructing a first meanline curve, and finding a first difference between the raw curve and the first meanline curve. The analyzing also includes constructing a reversal curve by calculating a second derivative of a meanline curve constructed from the set of data points. The method also includes deciding the acceptability of the feature of the article.

Abstract: A method for welding a first powder metallurgical (PM) part to a second powder metallurgical (PM) part includes: working a first face of the first PM part; working a first face of the second PM part; and friction welding the first face of the first part to the first face of the second part.

Abstract: An airfoil including an airfoil body, a recessed portion of a first depth in a first side of the airfoil body, the recessed portion including a plurality of pockets of a second depth located within the recessed portion and ribs of the first depth located between the pockets, a cover configured to fit into the recessed portion such that an interior surface of the cover engages the ribs and an exterior surface of the cover is about flush with an exterior surface of the first side of the airfoil body, and a high energy beam weld configuration extending through the cover and into the ribs and positioned to attach the cover to the ribs.

Abstract: Aspects of the disclosure are directed to a first chip ring that includes a first through slot, a second chip ring that includes a second through slot, and a component disposed between the first chip ring and the second chip ring that includes a component through slot, where the first, second and component through slots are coaxial along a slot axis this is oriented at a non-zero valued angle relative to a planar surface of the component facing at least one of the first and second chip rings.

Abstract: A multi-axis machine includes a controller operable to control a nozzle which ejects a particulate material relative to a part surface to maintain a compound angle and predetermined stand off distance to remove surface and near-surface crack initiation sites.

Abstract: A pull type swather having double swath and enhanced operating to transport mode change capabilities. A subframe is mounted forwardly of a rear frame and the two are pivotally connected. The table of the swather includes a pair of draper decks operable to be independently moved relative to each other and to the table. A hitch is pivotally connected to the subframe and a hydraulic cylinder is operable to adjust the angle of the hitch relative to the table. The subframe is locked to the rear frame during operation and until the transport mode in desired wherein the subframe is unlocked and pivoted relative to the rear frame. Provision is made for automatically interchanging between the transport and operating modes.

Abstract: A low profile axial flow combine with a low center of gravity for improved stability, with reduced overall machine height for ease of shipping and with high capacity grain tank of the saddle type. A threshing and separating rotor, in coaxial relationship to a rotor casing, extends longitudinally and approximately horizontally in the combine to the discharge end for low rotor discharge of the threshed materials. Cleaning apparatus including the grain pan, the separator pan, the chaffer, the sieve screen and the blower are compactly nested beneath the rotor casing. A high capacity saddle grain tank extends over and down opposite sides of the rotor casing. A discharge auger extends transversely through the boots of the grain tank and through an auger housing interconnecting the boots. The upper end of the grain pan extends over the auger housing interconnecting the grain tank boots. The lower end of the grain pan is stepped.
